Hi, my name is Oscar and I was interested in this flyer because I recently came across a Sterling silver rule and I wanted to learn how to use it. I had absolutely no idea how old this mathematics tool is and it's amazing to me that it was manufactured in the early seventies. Thankyou for allowing the public to see these amazing parts of history that we all seem to forget.
